Hi Paul
It is some time since the last post since I had virtually given up getting 3 screens to work again on my Surface Pro 3.  But it seems that the recent Surface Pro 3 System Hardware and Firmware updates have fixed “something” so that now 3 displays work again using the CSV-5400 with 1 HDMI and 2 DVI, despite Microsoft Surface Support never acknowledging that they ever had a problem.  Using the Surface display with 2 external displays works as well. Thanks very much for all your help. Regards Richard

I have contacted Microsoft Surface Support again who have said they can not help any further as the Hub configuration is not officially supported.  As Club-3D advertise the Hub connected to a Surface pro with 3 displays I am utterly frustrated that no one can offer a solution

Hi Paul
Yes I disconnected the Surface display before connecting the 2nd external.  The SP3 i7 is also supposed to drive the Surface  display + 2 external in your table above and it wont do that either.

Hi Paul
I have returned my CSV-5400 to Club-3D and have got the firmware updated but sadly it has still not fixed the problem.  I am now back to square one, only 2 displays will work concurrently and 2 HDMI + 1 DVI or 1 HDMI + 2 DVI wont.  Any further suggestions?

Thanks, those are way more than i would want to spend. I was purely thinking of a relatively cheap contingency plan to get 3 displays working on my Surface Pro 3 + Microsoft docking station having invested in the CSV-5400 in case the firmware upgrade doesn’t provide the solution. So you wouldn’t recommend the CSV-2302 USB 3.0 to Displayport 4K Graphics Adapter which is £84 GBP to drive the CSV-5400 connected displays?

Hi Paul
When you said discreet I was thinking card external that I could plug into the docking station using USB3 and then displayport to the CSV-5400 with 2 HDMI and 1 DVI displays. The main use is for workflow productivity with simultaneous access to Office 365 apps, browsing and one display streaming 1080p video.

Thanks I will contact my supplier TechDNA.co.uk first as I am based in the UK.
If I did go for a discreet graphics solution which card would you recommend?

[RichardN]

Its wrapped round the flying lead
BSV-5400
REV:A0-2.1 FW:041A
1448

All Microsoft support could suggest was refreshing windows which I have done but there is no change, 3 screens will not configure

Hi Paul

Following endless trouble shooting and swapping cables I still cant get the CSV-5400 to work properly. It wont even support 2 screens on HDMI at all. When it was working with 1 HDMI and 1 DVI and I swapped the MDP2DP6IN 6 inch input cable to a MDP2DPMF3 that was 3 ft long  and specified to work at 21.6 GBbps it would not sync to the 2 screens again.  I confirm that I have pressed the scan button appropriately. All these troubles only started on 18th Jan ie after the graphics card was updated to v10.18.14.4029 and I am now wondering if that is the root cause. even though it seems ok on your surface 2.

Hi Paul

Thanks I have got all the updates applied and have now swapped my CSV-5300 for a CSV-4000 with new cables to see if the updated technology would help but I’m still stuck with only 2 displays working concurrently at any resolution.  My configuration sequence is
Surface Pro 3-i7-500GB powered up.
mDP-DP passive adaptor connected to Surface mDP port and CSV-5400 powered up.
CSV-5400 DP Port 1 DP-HDMI passive adaptor connected to Dell ST2420L display and set as main display. Surface display disconnected in display settings.
CSV-5400 DP Port 2 DP-DVI passive adaptor connected to Dell ST2210 display.
Duplicate desktop in display settings then extend desktop to Dell ST2210. Both displays working OK at 1920 x 1080 resolution so far.
CSV-5400 DP Port 3 DP-DVI passive adaptor connected to Dell 2009W display. Displays all recognised in display settings but any attempt to duplicate or extend the desktop to the 3rd display fail whatever the resolution.  The same happens in any combination of ports on the CSV-5400 or order the displays are connected in.

Any suggestions?

My surface pro 3 / MST CSV-5300 set up with 1 HDMI and 2 DVI screens and docking station which has been working OK since 19th Dec has suddenly started having a similar problem following a wake from sleep in the dock.  I now cant get it to drive 3 screens at all ( the best is 1 DVI screen not the HDMI) whether dock connected or plugged directly into the Surface despite reboots in or out of the dock. I have checked the screens and cables individually.  Any suggestions or am I going to have to return the MST under warranty?
